| 425063000 | BUILDING FORMS OR CONSTRUCTION ENGINEERING TYPE MOLD WITH REPOSITIONING MEANS FOR PROGRESSIVE MOLDING | 7 |
| 20090041879 | Self-Raising Form Control System and Method - A self-raising form control system and method is provided that that may be used to form elevator shafts and other vertical building structures. The apparatus includes one or more form elements for defining an area to receive a formable material, such as concrete. Each element is attached to the form structure. A lift apparatus is provided for lifting the form elements. The lift apparatus comprises a measurement device for measuring the position of said lift apparatus relative to a fixed point. The lift apparatus is connected to the form structure. A control unit is provided for controlling the lift apparatus. The control unit is signal connected to the measurement device and is signal connected to the lift apparatus. | 02-12-2009 |
| 20110171336 | TRACK-GUIDED SELF-CLIMBING SHUTTERING SYSTEM WITH CLIMBING RAIL EXTENSION PIECES - In a rail-guided self-climbing formwork system | 07-14-2011 |
| 20110223272 | APPARATUS FOR SLIPFORM CASTING - Apparatus for slipform casting particularly of a moulded concrete structure including a slipform yoke having at least one pair of yoke legs in opposite disposal, at least one pair of form halves connected to the yoke legs between which form halves concrete is poured and at least one jack pipe interacting with the yoke, wherein the jack pipe is hollow. | 09-15-2011 |
| 20110038972 | Apparatus for Manufacturing a Pre-Cast Retaining Wall - An adjustable mold for manufacturing a pre-cast cantilevered concrete retaining wall. The adjustable mold includes a base, at least one upright form disposed substantially perpendicular and adjacent to the base, and a plurality of rails interchangeable and repositionable adapted to be secured to the base to vary the size and surface features of the retaining wall. The base, the upright form, and the plurality of rails cooperate to define a plurality cavities in fluid communication that shape and allow sufficient curing of a combination of fluid concrete and concrete reinforcement to form a retaining wall of a selected configuration. A top surface of the base is contoured to define the mold negative of a textured shape desirable for the external surface of the pre-cast cantilevered concrete retaining wall. | 02-17-2011 |

| 20080274220 | Portable Concrete Moulding Machine - A portable concrete molding machine can extrude concrete moldings of a range of widths by the provision of one or more tunnel plates within the mold, the machine being provided with respective pusher plates that have pusher faces of widths complementary to the effective widths of the mold. A pair of links connect a gearbox to the pendulum arms of the pusher means to ensure even driving force applied to the pusher plates as they undergo reciprocating movement to allow concrete to flow from a hopper through a mouth of the mold and to extrude the concrete from the mold, the machine being advanced in an extrusion direction by the extrusion of the concrete from the mold. | 11-06-2008 |
| 20090053345 | Concrete slip forming device - The present invention is an improved slip forming device for forming a concrete curb having a desired profile. The device consists of a hopper portion and a removeable extruder portion, the extruder portion being adapted and configured to extrude the concrete curb having the desired profile. The hopper portion of the invention has a top, an open bottom, side walls and a back wall having an opening. The extruder portion of the invention has a front wall, a back wall, a closed top, and open bottom and side walls. The front wall of the extruder has a front opening and the back wall of the extruder has a rear opening, the top and side walls of the extruder forming a channel between the front and rear openings of the extruder. The rear opening of the extruder is substantially in the form of the desired profile. The front wall of the extruder is releasably mounted to the back wall of the hopper such that the front opening of the extruder is in communication with the opening of the hopper. The device includes a pair of mounting arms mounted to the hopper and extending away from the hopper, the extruder being mounted to the support arms. The extruder is releasably mounted to the hopper by means of a plurality of mounting flanges positioned on the back wall of the hopper and the front wall of the extruder, the mounting flanges being held together by mounting bolts. | 02-26-2009 |
| 20100260878 | AUGER FEEDER FOR CONCRETE MIX, METHOD OF MANUFACTURING THE AUGER FEEDER, AND SLIPFORM-CASTING APPARATUS - An auger feeder for concrete mix, comprising a helical segment ( | 10-14-2010 |
